Critical reception
Vince Bellino of Decibel Magazine stated that the group has "earned a reputation up and down the east coast for their fierce political message and chaotic live shows". Metal Injection reviewed Clever Girl as "10/10" and referred to the album as "an explosive hardcore record that packs tons of aggressive blends of sound, and shows off lots of impressive techniques in the instrumental playing" as well as "an educational experience: for the things happening around us, the fears we’ve never had to experience, or the issues we may have not even been aware of".
